After i did the Multi Image Loader AS2.0,
I wanted to make an AS3.0 version of the class.

USAGE:
var multi:MultiImageLoader = MultiImageLoader.getInstance();
multi.addEventListener( MultiImageLoader.IMAGE_LOAD_START , onImageStart );
multi.addEventListener( MultiImageLoader.IMAGE_LOAD_PROGRESS , onImageProgress );
multi.addEventListener( MultiImageLoader.IMAGE_LOAD_COMPLETE , onImageComplete );
multi.addEventListener( MultiImageLoader.MULTI_LOAD_START, onMultiStart );
multi.addEventListener( MultiImageLoader.MULTI_LOAD_COMPLETE, onMultiComplete );
multi.store( photoContainer_01, “img/img_01.png”, “myPhotoId” );
multi.store( photoContainer_02, “img/img_02.png”, “myPhotoId2″ );
//Use: image container, image address, image ID ( for later referrence ).
multi.startLoad();
EVENTS:
- IMAGE_LOAD_START
